Apple won't use Intel's chips unless it would provide them significant benefits - what it doesn't at the moment and most likely won't in the years coming (if ever). One has still to consider the performance penalty x86 emulation would cause on iOS due to the missing virtual machine/just in time compilation when compared to Android.
What Apple may be interested in is using Intel's fab lead for their own SoCs. Especially if the Finfets are looking to be late next year by the foundries. Intel's 14nm process is a safe bet there and would help Apple to position the iPhone way ahead of all the others performance-wise. A destinction Apple desperately needs to make people continue to pay prices up to 1000$ for a phone. The rumor of reactivating Intel's mothballed fab fits perfectly into that picture. Maybe that's part of the reason Intel's share price did rise so much in the last weeks. Recovering PC business simply isn't enough to justify it in my opinion.
You misunderstood me, I mean Apple using Intel as a foundry like TSMC. The point about Intel's 10nm is that it could offer a one year cadence from the foundries FinFet processes to Apple and will be more than twice as small as 14/16FF which are still using a 20nm back-end layout in reality. This could be an easy $10+ profit per chip for Intel.
